Your secondary looks miles out. Should be centered under focuser drawtube as the other forum guy indicates.
Also, just a suggestion maybe start new thread with name like "secondary mirror collimation offset problem, help needed" as then this will alert many of the experienced guys on this site of your problem. (your current title maybe not asking for the help you want)

Thanks Richard,
I'm OK - I'm getting plenty of help.
It looks like that dimple plate is for another telescope secondary mirror hub.
The screws should have been rounded to fit into the dimples
but when it didn't line up they just reversed it and didn't care.
I am making a 15mm thick round spacer for the 3 adjustment screws -
and I'll get a longer 6mm thread - M6 Allen head bolt for the center part.
cheers
Allan
